UFO Sighting in Singapore, on January 6th 2015 – The pulsation was between 2-3 craft with slow but completely irregular changes in direction

4 of the staff were outside looking up towards SE- I went towards them it was approx 0530 AM End Dec 2014 Singapore- when I looked up they were easily 2-4 miles over the clouds- after 2-3 minutes I was aware I had seen these same type objects- up close in the late 70's from this instance- the pulsation was what reminded me of the previous event- the irregular flight and change of courses were pronounced after 10 further minutes- the cloud cover obscured the view- I was quite calm- I understand flight and technologies very keenly,
